Immu**assays have been central to biomedical research and clinical diag**stics, but their use requires large sample volumes as well as*expensive equipment and reagents to perform the tests. Microfluidic device have the potential to overcome these challenges, and a number of devices have been built that offer parallel processing, high sensitivity using small sample volumes, or the ability to screen for a wide number of markers. **ne have been able to have all three capabilities in one system, truly making microfluidics a viable option over traditional equipment.

The device is called “ELISA-on-a-chip,” and the researchers hope one of the early uses of the tech**logy will be to analyze cerebrospinal fluid since it holds clues about various underlying conditions but large Samples of it are hard to get.
